JOHN SCULLY, OF SOUTH AUBOY, NEV JERSEY.

MACHINE FOR UNLOADING CARS.

SPECIFICATION forming part of Letters Patent No. 394,727, dated December18, 1888.

Application filed June 20, 1888. Serial No. 277,630. (No model.)

To all whom it may concern:

Be it known that I, JOHN SCULLY, of South Amboy, in the county ofMiddlesex and State of New Jersey, have invented a new and ImprovedMachine for Unloading Cars, of which the following is a full, clear, andexact description.

This invention relates to certain improvements in Letters Patent No.366,033, which were granted to me July 5, 1887; and it consists,principally, in such construction of the machine that the shovels maybeshifted sidewis'e upon a stationary supporting-frame for carrying themto different positions in the car, and for carrying them from one trackto another in case the machine is used on a double-track road.

The invention also consists of the construction, arrangement, andcombination of the different parts of the machine, all as hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure l is afront elevation of the machine. Fig. 2 is a plan view. Fig.3 is a sectional elevation taken on the linew of Fig. 2, showing a carin position and the shovels partially lowered therein. Fig. 4 is anenlarged detailed front elevation showing the gearing for shifting theshovels laterally and showing the mechanism for raising and lowering andmoving the shovels to and from each other. Fig. 5 is a transversesectional elevation on the line y y of Fig. 4. Fig. 6 is an enlargeddetailed and sectional view of one of the traveling frames or carriagesand shovels, the section being taken on the lines of Fig. 7 and Fig. 7is a sectional elevation taken on the line ,2" .2" of Fig. (3.

A A represent two elevated and parallel bars supported above and acrossthe railway track or tracks B by the uprights or posts A A, so that saidbars constitute an overhead track for the traveling frame 0 to move uponfor shiftin the shovels D, held by said frame, to different lateralpositions in the car B to be unloaded, and for shifting said shovels toeither tracks. The said frame 0 is composed of the two parallel beams cc, mounted at their ends upon the trucks 0 c, and it is moved along thebars A A on said trucks by suitable mechanism under the control of theattendant, and hereinafter described, and the shovel-bars D, to whichthe shovels D are attached, are connected to the said traveling frame 0,and are adapted to be raised and lowered and moved to and from eachother by suitable mechanism, also under the control of the attendant andalso hereinafter fully de scribed.

About midway between and parallel with the bars A A are the centralbars, A A supported by the standards or frame A A, one at each side ofthe railway-track. The bars A form a central support for the travelingframe 0, (on which it is supported by the trucks 0 0 and this frame alsosupports or incloses an endless chain, E, by which the frame 0 isshifted sidewise. (See Fig. 5.) The said chain E is attached to theframe 0 and passes over the pulley a at the support A and over the twopulleys b b at the other end, and around the drum C, which is revolvedin either direction by the crank-shaft 0 through the medium of a trainof gearing, C (Shown clearly in Fig. 4.)

The shovel-bars D are each held or rather sustained in vertical positionby a carriage, F, placed upon and adapted to move or slide upon thetraveling frame 0. The said shovelbars D are each supported upon andoperated vertically by a rope, G, permanently secured at its outer endto a standard, g, and passed thence over the outer upper pulley, g, ofthe carriage F, thence down under a pulley, cl, at the side of the barD, thence up over the opposite upper pulley, githence around the twopulleys m" on suitable standards, near the center of the carriage (1,down to the rope G. (See Fig. 4.) The two ropes G (one from each of theshovel-bars) are connected to the rope G, which passes from the point ofconnection down under the pulleys i at the base of the frame A, andthence up to the drum H, journaled in suitable bearing attached to theupright frame A, as shown clearly in the figures. In this manner only asingle rope passes around the drum H, and by the revolution of this drumto wind up the rope the shovels and shovel-bars D D will be liftedvertically in the carriages F, and by reversing the drum to let out theropes G G the said shovels and bars may be lowered into the car B torest l upon the bottom thereof or upon any load or body of coal or othermaterial contained therein.

The drum ll is revolved from the powershaft J, through the medium of thefrictionwheel J, secured to the drum, and the smaller friction-wheel, Jattached to the shaft J by a spline, so that the said wheel J is adaptedto be moved upon the shaft. \Vhen the wheel J at its normal positionupon the shaft J no motion will. be transmitted to the drum ll, but whenthe said wheel is moved to the right or left by the lever J the groovesof the wheel J will impinge upon the grooves ot the wheel J and causethe drum ll to revolve and cause the elevation of the shovels. 3yreleasing thelever J the wheel J will alease the wheel J, and thuspermit the shovels to drop of their own weight. The lateral movement ot.wheel J is but slight, covering only what slight space there may bebetween. the surfaces of the grooves when there is no pressure on thelever J.

The shovels I), besides having the vertical movement just described andthe sidewise movement caused by the traveling of the frame 0 upon thecross bars or tracks A A, have also a l.)ack-and-torth movement to andfrom each other for sbiltingthe ltmdfrom the ends of the car to thediseharge-opening 13 (See Fig. 3.) This back-and-forth motion isproduced by the shaft K, pinion 7c, secured thereto by a feather, k, andthe two opposite rack-bars L L, secured to the carriages F F, as shownclearly in Fig. 3. The rack-bars L engage with opposite sides oi thepinion 7;, so that the revolution of said pinion imparts oppositemotionto the said racks, causing them to move the carriages F andshovel-bars and shovels simultaneously to or from each other, accordingto the direction of revolution of the shat'tK. The said rack-bars .l)are held in tirm engagement with the pinion It by the rods 1 1, securedto the upper and lower edges of the plates 0 e and the flangedanti-:t'rietion rollers I" Z, secured upon said rods, as shown clearlyin Figs. 33 and 5, and the shatftK isrevolvcd in this instance from thepower-shaft J by the vert ical shat't K, beveled gear-wheels M m at thetop, and the beveled gear M and reversing beveled gears m m at thelJOiLifOlll. The gears m m are arran ged on opposite sides of thegear-wheel M, and are connected to the power-shaft J by :t'eathers, an dare adapted to slide on said shali't, so that one or the other mayengage the gearovheel M, according to the direction it maybe desired tomove the shovels D. The gear-wheels m m are moved simultaneously by thehand-lever N and lever N, engagin the hubs of the said wheels andconnected together by the rod N as shown in Fig. 4, so that the movementof the hand-lever in either direction will engage one ff being providedwith wheels 7') at the top and p at the bottom, to run against the upperand. lower edges of the said plates c c, as shown clearly in Figs. tiand 7. The two blocks/"f" are united by the pairs of armsf f", reachingabove and below the block f and the pairs of diagonal braces f f", andthe block 1" is connected to the blocks ff by the side plates (1 q.(Shown in Figs. ti and 7.) The blocks f and ff are spaced from eachother to form a channel to receive and hold the shovel-bars l), and yetpermit them to have free vertical movement. At the top ot the block fare secured the two uprights [1, between which the pulley y or the ropeGis journaled.

At the lower ends of the arms f" is journaled the anti-Friction wheel.9, which braces and takes the strain of the Imekward thrust of theshovel-bar '1') when in operation, and the upper end of the shovel-barisheld firmly between the pulleys g y so that the same is braced and heldvby the carriage both above and below the traveling frame (l. \Vhen thetraveling frame (7 is moved sidewise by the endless chain E, the pinion7.' slides upon the long shaft K and li'mtther 7.", so that there can beno disconnection of the mechanism which operates the shovels to and fromeach other. Upon each of the ropes (St is placed a weight, I, (shown inFig. 'l,) to take up any slack in said ropes.

The shovels l) are each provided at their upper edge with a row oftines, d, to prevent. the shovels t'rom settling into the load too far.

l-Iaving thus fully described my invention, I claim as new and desire tosecureby Letters Patent- 1. In a maehinet'or unloading cars, thetravcling Frame (3 and the carriages i placed thereon and n-ovided withshovel-lmrs, in combination with the shaft K and connections with thecarriages l and means, substantially as described, for shitting thetravcling frame (1 upon its supports, as and for the purposes set forth.
